PiiDetector

type PiiDetector = "credit-card" | "email" | "phone" | "iban";

Deterministic PII detection + redaction over message text.

Detectors are conservative by default: credit-card (separator-tolerant, Luhn-validated so order/tracking numbers don’t false-positive) and email. phone and iban are opt-in because their shapes collide with order ids, reference codes, and similar commerce artifacts.
